SMOKE-CONSUMING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 260,894, dated July 11,1882.

Application filed April 3, 1832. (No model.)

To all whom it may concern:

Be it known that I, SIDNEY PARKER, of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inSmoke-Consuming Apparatus for Steam-Boilers; and I hereby declare thefollowing to be a full, clear, and exact description thereof, which willenable others skilled in the art thereto relating to make and use thesame, reference being had to theaccompanyingdrawings, forming a parthereof, and in which- Figure 1 represents aperspective View of a sectionof grate-bars, showing the pipe connecting to the steam-dome at one end,and superheater at the other end thereof, and the jet or blast. Fig. 2represents a plan View of a furnace, showing the apparatus in place; andFig. 3 is a side View of a boiler and furnace, showing the arrangementof the apparatus, the near wall and superheater being re moved.

Like letters of reference indicate like parts.

In the drawings, a-represents a section of grate-bars, which arepreferably constructed as shown, consisting of two end pieces connectedby three longitudinal bars, provided with a tubular opening, b,startingfrom the steampipe 0, through which the steam passes forward,thence across in the head-piece to the next bar, thence back through itand the rear end piece to the third grate-bar, and through the forwardend piece out into the pipe (I, passed under the grate-bars and outthrough an opening in the side wall, and then up and returned throughthe wall into a superheater, e, which consists of an iron box providedwith tubular passages, (shown dotted,) so as to subject the steam to alarge heating-surface, whereby the steam is superheated, and also at thesame time given increased force as it issues from the jet f over thefire in the furnace. The object of passing the steam through thegrate-bars before passing it into the superheater is twofold: first, toprevent them from burning, and, second, at the same time make partbefore it enters into the apparatus 6. The jet f is taken from the rearside of the superheater c by a pipe, f, passing outward through thewall, where it is connected to a curve, f from which a return-piece, for pipe parallel to the first, again projects through the wall into thefurnace. The end of said pipe is provided with a jet, f, in the form ofa horizontal slot, from which the steam issues in a broad jet over thefire and, as shown, in one corner of the furnace. The object of passingthe pipes d and f and f through the wall, as shown, is to protect themfrom the fire, and particularly so for the pipes f and f, as in case thejet becomes injured it may be replaced at any moment while the apparatusis in operation.

The apparatus 6 is placed into or near one corner of the furnace, asshown, and receives steam througha pipe, 0, and section of gratebars, asshown. In a diagonally-opposite corner of the furnace, as shown, isplaced a similar apparatus, 0, which also receives its steam from apipe, either independently attached to the steam-dome or branched from amain pipe, and whichis supplied with steam passed through a like sectionof gratebars, a, placed upon the same side of the furnace with itssuperheater 6. Thus arranged, each section of grate-bars and itssuperheater works independently of the opposite one; but it is thesimultaneous operation of the two jets f at the same time blowing acrossthe furnace in opposite or nearly opposite directions that will cause arotary motion of the smoke and gases as they rise before passing overthe bridge-wall, and thus retain them longer over the fire and thus beconsumed. 8 I

The jets are shown passing through the walls at right angles to saidwalls, and which is preferable; but they might curve so as to point moreor less toward the center of the furnace, onlyvnot so far as to causethejets to blow against each other, and thereby prevent the rotarymotion described. Noxious gases may thus, with air, be fed to thefurnace and use of the heat to superheat the steam in I completelyconsumed or changed when they are emitted from the smoke-stack. A cock,c, y 2.
